LlamaIndex Review 2026 — Best Open-Source RAG Framework

In inglese

LlamaIndex gives developers Python and TypeScript SDKs, connectors, indexing, retrieval, memory, state management, human-in-the-loop components, and agent-building tools. It supports conversational applications, RAG systems, structured extraction, and multi-step workflows.

The core framework is open source and free to use. LlamaParse and related hosted document-processing services are separate paid products with credit-based pricing; enterprise features and higher usage cost extra.
